An autoinflator for automatically actuating a gas cartridge upon sensing of water. The autoinflator includes a fusible link actuator assembly positioned within a longitudinal bore. The fusible link assembly includes an actuator housing with a blind link hole, an actuator cap, and a pair of retaining balls protruding from the sides of said actuator housing which engage into a corresponding slot in the longitudinal bore to retain the actuator housing in a cocked position. A slidable link, positioned within the blind link hole, includes an annular groove positioned about its circumference at a rearward portion thereof and a taper positioned at a forward position thereof. A fusible link interconnects the actuator cap and the slidable link for retaining the slidable link rearwardly in a cocked position within the blind link hole. Upon being supplied electrical current when submersion in water is sensed, the fusible link is melted, and the retaining balls engage into the annular groove of the slidable link thereby causing actuation of the gas cartridge.

Electric autoinflator

An electric autoinflator for inflating inflatable devices such as personal flotation devices, life rafts, buoys and emergency signalling equipment. The electric autoinflator comprises an actuator assembly including a fusible link. A water-sensing electrical circuit and battery supplies electrical current to the fusible link actuator assembly upon immersion in water for a predetermined period of time. Upon fusing of the link, the actuator assembly forcibly causes a firing pin of the inflator to pierce the frangible seal of a compressed gas cartridge. The escaping gas then inflates the inflatable device.

A check valve having a presettable cracking pressure. The check valve employs a spring-loaded valve element in which the compression spring and valve element are held into position in the valve body by means of an apertured plug.
